About:

The dis module supports the analysis of CPython bytecode by disassembling
it. The CPython bytecode which this module takes as an input is defined in
the file Include/opcode.h and used by the compiler and the interpreter.


Source Code:

import dis



def print_hello(string):

    print("Hello", string)



# This will display the disassembly of print_hello

dis.dis(print_hello)


Output:

  4           0 LOAD_GLOBAL              0 (print)

              2 LOAD_CONST               1 ('Hello')

              4 LOAD_FAST                0 (string)

              6 CALL_FUNCTION            2

              8 POP_TOP

             10 LOAD_CONST               0 (None)

             12 RETURN_VALUE
